Overview
Multi-way Operation
The CH-250 Passive Infrared (PIR) Multi-way
Vacancy Sensor provides automatic lighting shutoff
for a variety of applications including those with
multiple switch locations. It is engineered to
comply with specific provisions of California’s Title
24-2013 energy code.
A CH-250 connected to other CH-250s and/
or RH-253 Decorator Single Pole Momentary
Switches provides true multi-way on/off control.
An occupant simply presses the on/off pushbutton
of any connected device to turn on the lighting.
Lights remain on as long as one of the CH-250s
continues to detect occupancy. The user may turn
off the lighting by pressing the on/off button on
any of the connected devices. If the room becomes
vacant and lights are on, they will be switched off
automatically following the time delay of the last
CH-250 to detect occupancy.
Operation
The CH-250 operates as a manual-on sensor.
Users must press the pushbutton to turn on
lighting. The CH-250 employs PIR technology to
sense the difference between the infrared energy
from a person in motion and the background
space. It keeps lighting on as long as motion is
detected and provides automatic shutoff, following
a user-selected time delay, when motion is no
longer detected. Users may turn the connected
load off manually.

Applications
CH-250s are appropriate for residential and light
commercial applications where the switch location
has an unobstructed line of sight of the room.
Multiple CH-250s are ideal for hallways, stairwells
and large rooms with multiple entrances, as each
sensor expands the coverage area.
